Well I'm still stuck here.
My goal is to display the camera coordinates on screen using A HUD. I Start with osgHUD example. everything went fine , the error occur when I'm changing the text, after several frame it just crash. I tried updating the osgText in the DrawableUpdateCallback, tried in the --- while (!viewer.done()) ---- loop, and yet the same error.
Did you set DYNAMIC datavariance on the text drawable you're changing?
See e.g. the thread with subject "osgText crash", dated 8 oct 2008, for what might be going on here...
